489283 ÷ 12 
We want to figure out the number of times 489283 can be divided by 12.

Going ahead to step 1:
12 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 12

Step 2:
When dividing 48 by 12, we get 4 with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 48 away from 48, we end up with 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 12

Step 3:
The number 12 fits into 9 0 times, leaving a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 40.0
Deduct 0 from 9 and we're left with 9.
Fetch the next digit (2) from the dividend, attach it to 9 and continue: 92 / 12

Let's proceed to step 4:
If we divide 92 by 12, we get 7 and a remainder of 8.
The number 7 becomes the next digit in our result. 
Result so far: 407.0
If we subtract 84 from 92, we get 8.
Fetch the next digit (8) from the dividend, attach it to 8 and continue: 88 / 12

Going ahead to step 5:
12 goes into 88 7 times with a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 4077.0
If we take 84 away from 88, we end up with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 12

Let's proceed to step 6:
The number 12 fits into 43 3 times, leaving a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 40773.0
Subtracting 36 from 43 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 7:
When dividing 70 by 12, we get 5 with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 40773.5
Deduct 60 from 70 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
100 divided by 12 is 8 with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 40773.58
Subtract 96 from 100 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 9:
12 goes into 40 3 times with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 40773.583
If we take 36 away from 40, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 10:
12 goes into 40 3 times with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 40773.5833
The remainder is 4 after subtracting 36 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

In conclusion, the division gives 40773.5833 with a balance of 4e-05.
